Pekin Duck Problems

I have 3 Peking ducks and they are about 6 months old. This week I noticed one of them limping and favoring one foot. It looks like it could be infected but I'm not sure. Does anyone know what this looks like? And what I can do to help her?

It looks like your duck may be suffering from Bumblefoot, but I am certainly not a duck person, nor a vet. You may want to use the search bar to look up bumble foot. You may also want to post on the duck forum or emergencies forum to try and figure out for sure what is going on. Good luck!
